Description
【Technical field】
The utility model is about a kind of power winch overcurrent safety device, mainly aobvious set by power winch
Show the current setting value and current actual value that the power winch is shown on panel, automatically controlled group of the power winch is equipped with one second
Plug socket for a current regulator grafting and adjusts the current setting value, with promote the safety in utilization of the power winch and
Convenience.
【Background technology】
" power winch " is a kind of by power retractable cable wire, to sling and (further) or put down the lift heavy of (releasing) weight
Power utensil also has referred to as " hoist engine " or " lift heavy hoist engine ", and the place that known power winch is installed and used is hung just like high building
Hang weight (goods) object vertical lift use or be installed on jeep, on offroad vehicle for pull its vehicle or save oneself mobile (escaping danger) use.
Known power winch side is equipped with a power source (such as motor), and the power generated is driven by internal axis, drives one to set
In side is adjacent or the deceleration device effect of opposite side, inside the deceleration device by several levels slow down (such as planetary gear set is set) and
A cable pulley is driven to rotate after gearing, makes the cable wire being wound on the cable pulley that can make to rotate forward the action released or invert withdrawal,
That is, power winch is the rotating of cable pulley to be controlled to act using power, and cable wire is released or withdrawn further to control, this
Action i.e. for cable wire is put, received by power.Power winch is additionally provided with one automatically controlled group, generally (therefore is frequently referred to as automatically controlled into box-like body
Box) be electrically connected with the power source, and in the power winch surface be equipped with a power switch body, with control the power source with
Conducting (CLOSE) or disconnection (OPEN) between exterior power supply (such as vehicle accumulator)；This automatically controlled group can be via a plug socket and one
The wired hand held controller separately put does wired connection or this automatically controlled group wireless hand held controller that also can be separately put with one does nothing
Line connect, on wired hand held controller or the wireless hand held controller via with the automatically controlled group of online running,
Reach long distance and manipulate the effect that the power source starts or stops.
Known power winch is often arranged on vehicle, is escaped danger use as the disaster relief, therefore according to all multi-users
Empirical response, known power winch has the misgivings of following safety on operating with：
1. power winch using when can enable the voltage rapid decrease of vehicle accumulator (accumulator), proper use of mode is necessary
Start just use power winch during car engine (charging to storage battery), it is too low to avoid battery voltage, cause last vehicle
The awkward situation or even renvoi that can not start influence safety.But in actual use, often many operators ignore car engine at all
The importance that must start there may come a time when to be intended to processing emergency (for example race against time the disaster relief), so vehicle is flushed to now
After, as soon as electric switch pass is begun to using the power winch disaster relief (rescue people or rescue vehicle), forget necessity of vehicle startup at all, etc. calamities
Harm has been managed, and may suddenly send subsequent processing (suddenly sending to hospital) again, but result vehicle is with regard to motionless.These missings often occur,
To find out its cause, it is real because of the driving custom of the powered-down door of lower Chinese herbaceous peony this i.e. normal (daily so), and the disaster relief is occasionally, therefore forget to send out
Motor-car is just using the helpless of power winch actually human nature.It is most important to be, on known power winch ontology or at installing nearby all
It can not show the device of vehicle accumulator electricity, user is caused to be difficult to be alerted really it is noted that vehicle voltage amount.
2. power winch pulls weight because that must contribute, therefore its power source (such as motor) must endure as pole in effect
Big torsion, therefore inside easily increases temperature and causes the situation overheated power source in itself, in particular, when being hung using power winch
The use that overweight or dangerous situation such as draws at improper (urgent) situation is hung, power source electric current is more easily caused and rises sharply, it is opposite to cause power
Source hyperthermia and superheating situation, but known power winch is when in use, and user is not aware that the temperature inside power source, so having no way of
It determines when must to suspend use or stops using, therefore often lead to power source overheating fault, gently then scaling loss (damage) unit
Part is heavy then the safety problem that weight is reversely fallen occurs.
3. power winch is when in use, operator should be the personnel for most understanding cable wire direction (releasing or withdraw direction),
So sometimes more upper in the case of pitch-dark in the case of the urgent use, often operator also can be unclear suddenly
Why is Chu's cable wire direction, therefore causes to operate chaotic or malfunction situation generation, and the lighter only delays the disaster relief time, severe one
Probably renvoi further injures.
4. known power winch is provided with a power switch body in main body, with control power source and exterior power supply (such as
Vehicle accumulator) between conducting (CLOSE) or disconnect (OPEN), it is sometimes more upper in the colour of sky so in the case of urgent use
In the case of dim, often operator can not know yet and is on earth between power source and exterior power supply suddenly
(CLOSE) state or in (OPEN) state of disconnection, therefore cause to operate chaotic or malfunction situation and generate.
5. known power winch is had no any when using wireless hand held controller on-line operation on the power winch
It has been shown that, cause sometimes aid or onlooker because not knowing power winch whether there is startup on earth, and make improperly act (no early warning
Pass through or turn on the power source), the anti-injury for causing personnel or equipment.
For many safety concerns in above-mentioned power winch use, existing design at present power winch main body just
The product of one " display panel " is set to come out on face, which be electrically connected with automatically controlled group of power winch, this is aobvious
Show that panel generally can at least include:One dynamic start viewing area shows that the power winch is in the signal that shines and has been turned on electricity
The serviceable condition in source；One vehicle power supply electricity viewing area is to adopt luminous signal display with several blocks to install the power winch
Vehicle on the how many state of electric quantity of power supply；And a warning temperature viewing area, when the temperature of the power source reaches a setting value,
To shine, signal shows to alert the running that must stop power source.More preferably power winch display panel can then further include:One
Cable wire direction viewing area is to adopt progressive beat type with the signal that shines to light, shows cable wire direction of travel；And one radio operation show
Area is operated in a manner that the signal display power winch that shines has been converted into wireless remote control.
Operating state during power winch operation is clearly showed that setting one " display panel " in the main body of power winch
And relevent information, it allows the very clear grasp present situation of operator, the safety in utilization of power winch can be substantially improved really in this way.
But everybody is engaged in power winch design, the practical experience and power winch of manufacture work many decades with the present utility model application
The practical experience of user and demand feedback, it is believed that power winch is during actual use, except above-mentioned operating state and phase
Closing message, it is necessary to outside being clearly showed that on a display panel, " torque value " when still dynamic winch operates is also one very heavy
Should be by the message of real-time display.It is used the reason is that, the use of power winch is mainly born a heavy burden, so can generally be twisted in power
Interior portion sets " the torsion limiting mechanism " of an overload protection, in case when overload of bearing a heavy burden occurs in use for power winch
When, it can be acted on via " the torsion limiting mechanism ", transmission mechanism be enabled to disconnect power connector, to protect the driver in power winch
Structure (such as motor and deceleration mechanism etc.) is avoided because excessively overload causes failure to be damaged；It can also be set in known power winch simultaneously
One " unpowered braking mechanism " is put, (may be that operator stops from by stop key to work as power winch moment stopping power
Only or due to " the torsion limiting mechanism " acts on stop) when, can brake work be carried out to the transmission mechanism of the power winch at once
With, and weight is made to stay in the height, the danger situation of automatic descending unintentionally is avoided to occur.It follows that in power
In actual use, " torsion limiting mechanism " is a kind of critically important release mechanism to winch.
In current practice, power winch using existing " current over-load protector " as torsion limiting mechanism,
When principle is that loading torsion increases, power ource electric current can also increase, and torque value and current value are linear correspondences, therefore
A current setting value is set to power winch and is equal to one torque settings of setting, is set when the electric current of power winch reaches the electric current
During definite value, also reached equal to torsion it is critical, therefore detecting current value can the management and control power winch will not overload.It is but known dynamic
The security setting that " torsion limiting mechanism " is only passivity is somebody's turn to do in setting inside power winch, is usually twisted by manufacturing works according to power
Vehicle power size assigns a current setting value (corresponding to torque settings), therefore the power winch of each type has identical electricity
Setting value (corresponding to torque settings) is flowed, and to ensure safety, manufacturing works can all improve safety coefficient for setting value.
Therefore during practical operation power winch, shutdown is generated when triggering " the torsion limiting mechanism " due to electric current reaches the current setting value
During effect, actually often there is one section of current value (torque value) can be used.But at this time because power winch has stopped power, so
Weight can only be suspended in the air or be rested in the halfway of towing, and this situation passes through to remove causes big inconvenience to operator
Outside, while misgivings for security but will be caused.Thus, it can be known that known power winch is by current setting value immobilization, on using
It is aobvious to have inconvenience, it is to be improved.

Through how many electric current (equivalent that how much torsion used) is used very clear all to grasp.The overcurrent alerts viewing area
It 196 and is connect with a luminous signal and the buzzing sound, when not overloading using the power winch 1 normally, shown electric current is real
Actual value B should can be less than current setting value A, so this shines, signal and the buzzing sound all stop, but bearing when certain towing
When carrying overload, it just can be appreciated that current actual value B persistently rises during towing, set when current actual value B reaches the electric current
During definite value A, the luminous signal and the buzzing sound that are connected are sent out, and lose no time to shut down strain with warning.The utility model is designing
On when so that the current actual value B is reached current setting value A, the power can just be enabled to twist after one of short duration " delay time "
" torsion limiting mechanism " set by 1 inside of vehicle is acted on to disconnect power connection, and simultaneously switches off power supply shutdown, then waits for one section
It restores electricity again after " downtime ", decides whether to continue to operate or how to strain by operator.
For example, current setting value A is set as by certain manufacturing works by the power winch 1 of a certain type when manufacture
350 amperes, delay time is set as 3 seconds and downtime is set as 30 seconds, therefore on the display panel 19 of the power winch 1
The position for having a current setting value A shows the printed words or symbol of " 350 amperes ", while have one on the display panel 19
The position of current actual value B, to show the current actual value B during practical operation power winch 1.Therefore it is twisted using the power
During vehicle 1, operator is from the position of current setting value A on the display panel 19, you can knows that the electric current of 1 upper limit of power winch is set
Definite value A is " 350 amperes ", practical from electric current on the display panel 19 when then practical operation 1 towing of power winch loads
The position of value B, the current actual value B of operator, that is, can be known power winch 1 is how many, if current actual value B is always very
Less than " 350 amperes ", then it represents that the power winch 1 is still remote from overloading, and can feel at ease to bear a heavy burden for towing；If electric current in operation
Actual value B is very close to " 350 amperes ", then it represents that the power winch 1 is very close to overload, using above extremely careful；And when the electricity
When stream actual value B rises to " 350 amperes ", luminous signal and the buzzing sound that overcurrent warning viewing area 196 is connected are sent out
Go out warning, " torsion limiting mechanism " set by 1 inside of power winch is then enabled to act on disconnecting after 3 seconds (delay time)
Power links, and simultaneously switches off power supply shutdown, then restored electricity, so loads at this time still again after (downtime) using 30 seconds
Stop, so operator may determine whether to continue to operate or how to strain.
Current setting value A is as set by manufacturing works, and is to ensure safety, and manufacturing works set for the electric current
Value A can improve safety coefficient, therefore trigger " the torsion limitation machine when current actual value B reaches current setting value A
When structure " generates shutdown effect, actually often there is one section of torque value can be used.Therefore i.e. design can be via one for the utility model
Current regulator 174 is adjusted to be directed to current setting value A, such as Fig. 2,3 and previously described, this automatically controlled group 17 side appearances
One first plug socket 171 and one second plug socket 172 are equipped with, is all closed when not in use by a cover cap to reach waterproof effect,
In, it is the connection-peg grafting use for the controller 173 to unload the first plug socket 171 after removing cover, and after unloading and removing cover
The second plug socket 172 be for the current regulator 174 connection-peg grafting use；One is equipped in second plug socket 172 to insert
Hole (such as USB jack), and second plug socket 172 and this automatically controlled group 17 interior electricity set for current setting value A
